5.34 need 100% correct if you don't know don't accept it

P5.34 A mixture of 30mol% ethanol and 70mol% water is charged to an equilibrium flash tank, which is at 1 atm pressure. To what temperature should the tank be adjusted to produce exactly 50% vapor and 50% liquid? What are the liquid and vapor phase compositions at this temperature? Calculate the fractional recoveries of ethanol and water, and the separation factor. P5.35 You have a mixture of 30mol% benzene (C6H6)/70mol% toluene (C7H8) that you'd like to separate into two products: a benzene-rich product and a toluene-rich product. If the separation is carried out in a single-stage flash drum at 130C, what is the minimum allowable operating pressure
